Specification of Letters Patent.

Application filed April 1, 1915 Serial No. 18,522.

To all whom z'z may concern:

Be it known that I, BERTRAND A. PARKES, ofPhiladelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Singein g-Machines, whereof the following is aspecification, reference being the burners, the supply of combustibleis,

reduced to only enough to perpetuate the flame. To this end the controlof the supply of gas to the burner is made conditional upon the presenceor absence of an article to be singed upon each holder so that in case aholder does not carry an article to be singed, the increase of the gassupply does not occur. This I accomplish by means of an electriccircuit, including an electro-magnet, whereby the means for increasingthe gas supply are rende'red inoperative by the,

closing of the circuit, which circuit is completed through contactbetween the traveling holder, and a fixed contact, so that if the holdercarries an article, it is insulated from the contact and the circuit isnot closed, under which condition the travel of the holder effects therequired increase in the jet, as the article to -be singed approachesit.

In the accompanying drawings, Figure I, shows in side elevation amachine containing the essential operative parts of my de- Vice. Figs.II, III, and IV, are respectively a plan view, a side view and a frontview of the means for controlling the supply of combustible for thesingeing jets. F igs. V, and VI, are respectively -a side elevation anda ,sectional plan 'of the fixed contact of the electric circuit. Fig.VII, is a sectional view along the line VII, `VII,- Fig. III.

of the jet is occasioned. Fig. XI, is a similar sectional view along theline XI, XI, of Fig. Big. XII, is an enlarged view of the tail piece ofone of the holders.

Referring to Fig. I, the spiderframe 1,

rotates upon the shaft 2. Each arm of this spider frame carries a holder3, set off slightly from the plane of the spider frame, and Curved so asto occupy a peripheral relation to the rotating frame. Each holdercarries a tail piece 4, which is shown more in detail in Fig. XII, andwhich is setin` ad ustable relation thereto', by the set screws 5, whichhold the groove ofthe tail piece upon the tongue 6, which projects fromthe bottom of theholder. The tail piece carries a small roller 7,projectingvinto the plane which contains coperating parts of devices`for controlling the supply of gas to the.

burners, and it is the properly timed contact of this roller 7, with thecontrolling devices hereafter to be described, that effects theoperation of my machine to the end' which I have described.

The burner tubes 10, 10, and also sparkextinguishing rolls 9, 9, are seton either side of the path of the holder 3. The tubes are perforated forthe production of singeing jets by burning a miXture of gas and air,

supplied to the burner tubes by a miXer 11, A

which receives gas from the pipe 12, and air from the pipe 13. Both ofthese pipes have interposed within them control Valves 14, 14, which aresimultaneously operated by rotation of a rock shaft 15, to which thevalve,

spindlesare attached by the coupling collars 8, 8. Uponthis rock shaftis set the arm 16, pivotally connected by a link 17, with a bracket 18,set upon the rod 19, which has a lengthwise motion for the control ofthe valves for the supply of gas and air to the burners, the downwardmotion of the rod tending to' increase the supply of gas,

and the upward motion tending to decrease it. The extent'of this motionis limited SO that at-one'end of its play the burners receive the fullamount of gas required to produce an effective singeing jet, while atthe other end of its play, the supply is so reduced 'as' to leave onlythat slight amount required to perpetuate thelflame.

If preferred, the maingas flane of the perforated burners may beextinguished absolutely, but in that case a small pilot light is usedfor -relighting the main flames when the gas is again turned on.

Lowering of the flame is occasioned by contact of the roller 7, with thecam incline of a cam piece 20, set upon a sector bar 21,.

which is supported by pivotal connection with the link 22, pivoted tothe fixed piece 23, forming part of the frame of the Inachine. Thesector bar 21, is also pivotally connected with the'lever 24, pivotedcen-*` trally on the fixed bracket 25, and at its other end to the lowerend of the rod 19. By the coperation of these parts, whenever one of therollers 7, comes into contact with the cam piece 20, the rod 19, iselevated` so* 'capable of being set in any desired position I by the setscrew 28, as shown in Fig. XI.

The increase of the fiame is effected by contact of the roller 7, withthe inclined upper edge of a pivoted cam-piece 30, which nornally liesin the path of the roller. This cam-piece 30, forms part of a largerswinging bracket 31, pivoted at 32, and carrying an arm 33, connected bya link 34, with the rod 19, so that contact of the roller 7, with thecam-piece 30, effects rotation of the bracket 31, suflicient to depressthe rod and thereby increase the supply of gas; This contact is also sotimed that normally the contact of one of the rollers 7, with thecanpiece 30, occurs just before the holder is about to pass into theregion of the burners, which is the position in which the parts areshown in Fig. I.

By the coperation and properly timed arrangement of the parts thus fardescribed, successive contact of each roller 7, with the controllingapparatus described, increases and decreases the supply of combustibleso as to produce an effective singeing flame during, but only during,the passage of a holder between the burners. But it frequently happensthat the attendant fails to place an article to be singed upon each ofthe holders, as they rotate, and it is anend of my invention to supply afurther control whereby the passage of a holder not containing anyarticle into the region of the singeing burners, shall fail to effectthe increase in the supply of gas which would otherwise occur. This Iaccomplish as follows: An electric circuit 40, includes a brush 41,pressing against the metal ring 42, on the side of an insulated roller43.

`This roller is provided with a peripheral metallic contact 44, which iselectrically connected to the' ring 42, and also a flattened surface 45,which is not so electrically connectedf The roller 43, is mounted upon abracket-46, swinging upon an arm 47, set upon plate 48, which is securedto the fixed framework o-f the machine, with capacity for verticaladjustment by slot and bolt connection, as shown in Figs. I and V. Afurther slot and bolt adjustment at right angles to the above 'isprovided, between the plate 48, and the arm 47, (see Fig. V), so thatthe position of the roller in relation to theline of rotation' of theholders may be controlled with great'accuraoy. The roller 43, is furthergiven a yielding capacity by means of its pivotal mounting on the arm47, which carries a lug 49, which affords a resistance point for thecoiled spring 50, which exerts tension upon the arm 52, which 1s anintegral part of the swinging bracket horizontal position as shown inFig. I.

Each of the holders 3, is constructed of conductive material and thecircuit is completed through the m'etal framework of the machine, andthe conductor 63, through the coils of two electro-ma'gnets 64, andthence by the conductor 65, to the battery 66. When thus closed, theelectro-magnets attract the cam-piece 30, the lower edge of which ispivoted to piece 31, by the pivot 69, and draw it laterally out of 'theplane in which the roller 7, rotates. Accordingly, provided no articleis carried by the holder 60, the making of a circuit as thus described,prevents the passage of 'the roller 7, from effecting any increase ofthe supply of gas. If, however, an article of teXtile fabric, as foreXample, a stocking, as indicated at 60, Fig. I, has been stretched uponthe holder 3, the fabric acts as an insulator to prevent the contact ofthe surface of the holder with the roller 43, and accordingly thecontact of the roller 7, with the part 30, occurs with the correspondingcontrol of the valve supplying gas.

In order to limit the making of the circuit to that time when alone itis useful, the roller 43, is limited in its capacity for rotation byastop 70, upon reaching which the flat side of the roller, which is notin the circuit, is presented toward the passing holder. Even though thearticle to be singed is of small extent, covering only the upper end ofthe holder, it effects the required insulation long enough to turn thefiat side of the roller toward the holder, whereupon insulation is nolonger necessary.

The roller 43, is normally maintained in the position shown in 'thedrawings by means of a. stoplug 75, which engages one of the side armsofthe bracket 46, and is main- 46, and thus tends to hold the bracket inits tained in this position by a coiled spring 76, best shown in Fig.VI. This spring also serves to return the roller to its normal positionafter being partially rotated by contact with the holders.

The tail pieces 4, herein shown, are only employed to adapt the machinefor the singeing of half hose. In the singeing of full hose, the rollers7, are attached directly to the sides of the holders 3. The functions oftheir rollers are, however, the same in either case, the additionallength aflorded by the extensions serving only to further limit theperiod for the full gas supply in accordance with the article underconsideration.

I have spoken throughout the specification and claims of increasing anddecreasing the supply of combustible by the controlling means described.It will, of course, be understood that the supply of combustible may beclecreased to the point of eXtinction of the flame provided well-knownmeans for "e-ignition, such as a pilot light, are provided.

Having thus described my' invention, I Claim:

1. In a machine of the class described, the combination of holderscapable of carrying singeable articles; singeing burners; means forcarrying the holders successively into operative relation to theburners; means for increasing the supply of gas to the burners when aholder carrying an article approaches the region of the burners, and fordecreasing the sane when the holder leaves said region; and meanswhereby the approach of a holder carrying no article to be singedoccasions no increase in the gas supply.

2. In a machine of the class described, the combination of holderscapable of carrying singeable articles; singeing burners; means forcarrying the holders successively into operative relation to theburners; means whereby the approach to the burners of a holder carryingan article occasions a temporary increase of the flame of the burners,and means whereby a holder not carrying such an article is preventedfrom thus affecting the fiame, said means comprising an electriccircuit, with an electromagnet, whereby the flame increasing means arerendered inoperative by the closing of the circuit, which is completedby contact of a fixed element with a passing holder, unless said holdercarries an article which efects insulation of the holder from the fixedelement.

3. In a machine of the class described in which the approach of a holderto the singeing burners automatically occasions a temporary increase ofthe singeing fiame; means for preventing the holder from effecting this,'including an electric circuit which is completed by contact of atraveling holder With a fixed contact point, and also includes anelectromagnet which when energized by the circuit, renders the fiameincreasing means-inoperative, and means whereby the presence of anarticle to be singed upon the holder prevents the closing of the circuitbetween the fixed contact point and the holder.

4. In a machine of the class described, the combination of a rotatingframe with a succession of holders mounted thereon; singeing burners inproximity to which the rotation of the frame successively carries theholders; a valve for determining the supply of gas to the burners; aprojection in fixed relation of said rotating frame; a cam which isnormally in position to be struck by said projection as it'rotates withthe frame; connections whereby said cam when thus struck actuates theValve to increase the supply of gas to the burner; and means whereby aholder carrying no article to be singed moves said cam out of the planeof the rotating projection at the time when it would otherwise be struckthereby, substantially as described.

5. In a machine of the class described, in which the supply of gas tothe singeing burners is temporarily increased during the passage of anarticle to be singed between said burners; an electric circuit includingelectromagnets which by their action upon closing of the circuit preventsuch increase of the flame, said circuit including the metal shodsurface of the holder and the metal shod segment of a roller, mounted infixed relation to the machine, with which the surface of the holdercomes in contact and completes the circuit, unless its metal shodsurface is insulated by the presence thereon of a singeable article,said roller including also a flattened non-conducting segment whichprevents further rotation of the roller, and, therefore, possibleclosing of the circuit until the holder has passed away from the regionof the roller.

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsylv vania, this twenty-ninth day of March, 1915.
